Hi All,
Hope you can help, I have a problem with my boiler in that the valve that's used to top up the central heating pressure has a leak. It,s not leaking from the pipe connections but from the spindal on the tap. It was fine last year, then before winter it leaked when you opened the tap, now its just plain leaking.
I will be able to replace the valve but am wondering if I will have to empty the system to do this. Below are my crude drawings and technical diagrams:
Here the colours are:
Yellow: Gas inlet
blue: mains in
red: DHW flow
Green: Central Heating return
Purple: Central heating flow
brown: problem valve
I can obviously shut off the mains water at the house stopcock and the stopcock on the boiler.
My question is with the other side of the valve being attached to the central heating flow, will the all the radiators dump their load if I disconnect the valve there????
Thanks
Mark
